Ok, here goes, after cloning the project from GitHub, I was asked by NetBeans if would like to create a project, so I chose yes, then:
1) I chose "Java" under Categories and "Java Free-Form Project" under Projects
2) I created an Ant build file "build.xml" from sample on https://ant.apache.org/manual/using.html
3) After creating the project I moved the "build.xml" to directory "nbproject" and updated "nbproject/project.xml" to point to the new build file destination
4) I updated the "build.xml" tasks to copy source files and license file in case of build and zip the build files in case of distribution
5) Finally I had to add a ".gitignore" fie to the root directory to ignore the "build" and "dist" directories from Git
After this I commited and pushed the whole NB project to GitHub you can find the final files here https://github.com/asaeles/sql_runner
